Detailed description of the invention
The display panels of the present invention explained in detail below.Fig. 3 to Fig. 7 is the figure that various embodiments of the present invention are described, as it is shown on figure 3, the display panels of the present invention can be preferably by being formed the situation of the lateral margin to panel LCD in the lightproof area of the display part DP periphery that will be located in panel LCD.Each reference described in Fig. 3 is identical with Fig. 1, the most in this description will be omitted.Fig. 4 A to Fig. 7 represents the enlarged drawing in the dotted line frame B of the display panels LCD of Fig. 3.
It is a feature of the present invention that, will be formed with the CF substrate S1 of color filter and be formed with the TFT substrate S2 coincidence of thin-film transistor circuit, and between two substrates in the display panels LCD of encapsulated liquid crystals, the lightproof area BM of black is formed in the frame portion of this CF substrate S1, and there is the identification labelling M described with negative-appearing image (negativepattern) in the local of this lightproof area, in this TFT substrate S2, it is configured with metal film MT1～4 in the position of the light shading that will transmit through this identification labelling.
The 1st embodiment of display panels LCD is represented in Fig. 4 A～Fig. 4 C.As Fig. 4 B, form identification labelling M at the lightproof area BM of CF substrate S1 with negative-appearing image.Resist pattern can be utilized to concurrently form this identification labelling when forming lightproof area BM.Additionally, in figure 4b, a part of lightproof area BM is cut into L-shaped (on whole panel, be cut into a mouthful shape in the way of surrounding display part along frame portion).So it is disposed to prevent moisture from entering in panel along photomasks such as black matrix"s from outside.
On the other hand, in TFT substrate S2, as shown in Figure 4 A, in addition to the general metallic patterns such as wiring, it is formed with metal film MT1 in the position corresponding with the identification labelling on CF substrate S1.It is configured to relative to metallic pattern MT such as above-mentioned, the gap of L-shaped (mouth shape) lightproof area BM, the wirings of configuration TFT substrate, to maintain light-proofness.
By TFT substrate S2 of Fig. 4 A and the CF substrate S1 of Fig. 4 B are overlapped, as Fig. 4 C, when observing from the face side of panel LCD, it is possible to substantially ensure that the state of the light-proofness of lightproof area, it is possible to visually constitute and identify labelling.
It addition, in Figure 4 A, configure (floating (floating)) by electrically separated with other metallic patterns formed on the tft substrate for metal film MT1.In such a configuration, it is possible to suppress the existence due to metal film MT1 that wiring etc. produces the impact of electricity.
Fig. 5 A～Fig. 5 C is the figure of the 2nd embodiment of the display panels LCD that the present invention is described.Different from Fig. 4 A～4C, as Fig. 5 A, the part being configured to metal film MT2 and other metallic patterns that will be formed in TFT substrate S1 electrically connects, to realize the ground connection of metal film MT2 especially.Thereby, it is possible to prevent from putting aside electrostatic etc. on metal film MT2.
Fig. 6 A～Fig. 6 C is the figure of the 3rd embodiment of the display panels LCD that the present invention is described.Different from Fig. 4 A～Fig. 4 C etc., as shown in Figure 6A, the metal film MT3 being formed in TFT substrate S1 is formed on the local of the metallic pattern of the slit SL of multiple opening, is removed (filling with metal film) at a part of slit SL of the position corresponding with identifying labelling.
So, by utilizing existing metallic pattern, it is not necessary to additionally guarantee to configure the position of the metal film corresponding with identifying labelling, it is also possible to realize narrow frame further.Additionally, the metallic pattern being formed with slit as Fig. 6 A is used as the path etc. for the illumination light making light-cured resin solidify, wherein CF substrate S1 and TFT substrate S2 are sealed by light-cured resin.
It addition, in the case of the part that the metallic pattern being formed with slit as Fig. 6 A is wiring, owing to arranging metal film MT3, the resistance value of local changes.In order to suppress this unfavorable condition, it is also possible in overall wiring, form identical metal film (removing the region of slit) at the position symmetrical with metal film MT3 point symmetry or line, adjust the balance of the distribution of the resistance value of metallic pattern.
Fig. 7 is the figure of the 4th embodiment of the display panels LCD that the present invention is described.Different from Fig. 6 A～Fig. 6 C, about being formed with the metallic pattern MT4 of slit, utilize figure as in the past, and do not use the metallic pattern MT3 being formed with the part removing slit as Fig. 6 A, in order to identify labelling.Therefore, not only without designing new metallic pattern, it is also possible to the change of suppression resistance value.
In the figure 7, the identification labelling M1 being formed on CF substrate is formed as follows, it may be assumed that by avoiding the position of the slit of metallic pattern, in the part corresponding with the metal film between slit and slit, optionally removes the photomask of lightproof area and is formed.The aggregation of the opening so formed constitutes identification labelling.
As described above, in accordance with the invention it is possible to provide a kind of display panels, it is possible to formed while realizing narrow frame and identify labelling.
